如何根据年份使用数据填充Crystal Reports [英] How to populate Crystal Reports with data depending on year

问题描述

我正在设计一份CR报告，我拥有数据库中的所有字段。数据库很大，但所有数据都有一年的数据。我想为用户打印2014年的数据，该怎么做？示例：

用户|车里程|步行里程|运行里程|年| 
 100 | 2000年| 3000 | 1000 | 2012 | 
 100 | 800 | 74 | 520 | 2013 | 
 100 | 500 | 88 | 528 | 2014 | 

因此，在报告中我只希望报告显示2014年的所有数据。可以这样做在CR 2013上？

解决方案

是的，您可以使用选择公式来过滤CR中的数据

  string  selectFormula =   {Report.Fieldname} = 2013​​; 
 crystalReportViewer.SelectionFormula = selectFormula; 

你可以像这样通过年份

 < span class =code-keyword> int  year =  2013 ; 
  string  selectFormula =   {Report.Fieldname } = +年; 
 crystalReportViewer.SelectionFormula = selectFormula; 

一些有用的信息可以从这里和此处

I have a CR report that I am designing and I have all of my fields from the database. The database is a large one but all of the data has a year in it. I want to print out year 2014 data for a user, how will that go? Example:

User | Car Miles | Walk Miles | Run Miles | Year |
100  | 2000      | 3000       | 1000      | 2012 |
100  | 800       | 74         | 520       | 2013 |
100  | 500       | 88         | 528       | 2014 |

So, on the report I just want the report to display all the data that has the Year 2014. Can this be done on CR 2013?

解决方案

Yes, you can use Selection Formula to filter your data in CR

string selectFormula = "{Report.Fieldname} = 2013 ";
crystalReportViewer.SelectionFormula = selectFormula;

you can pass the Year like this also

int year = 2013;
string selectFormula = "{Report.Fieldname} =" +year;
crystalReportViewer.SelectionFormula = selectFormula;
